[BioC] ANOVA for gene ontology analysis

I would like to test the significance of GO terms using ANOVA. Correct
me if I'm wrong, but I think that it makes sense to make a three
factorial ANOVA (where genes are one factor,  the experimental group
is the other, and the specific sample is the third) on a group of
selected genes (for example, group of genes belonging to a given GO
annotation group).

Clearly, this approach might have less power in case of small sample
sizes, but could be better than enrichment tests for larger sample

Is there an R package that can use the existing annotation
environments for running ANOVA?

Kind regards,
